Boiler Efficiency — What Gross and Net Efficiency Mean

The gross heat energy (total heat) from the combustion gases has two components; about 90% is sensible heat (heat which can be sensed or felt) and about 10% is latent heat. Latent heat is the energy which keeps the water vapour (produced by combustion) in a vapour state so that it passes out of the flue and doesn't all condense inside the boiler.
